How Safety Radar Works
Note: some of the safety messages
have been condensed, so each message
can be displayed on one or two screens on
Passport’s eight character display.
Since Safety radar technology is rela-
tively new and the number of transmitters
in operation is not yet widespread, you will
not receive Safety signals on a daily basis
and should not be surprised to encounter
emergency vehicles, road hazards and rail-
road crossings that are unequipped with
these transmitters and, therefore, fail to
provide a signal. As Safety transmitters
become more prevalent (the number of
operating transmitters is growing every
day), these Safety radar signals will be-
come more common.

How Safety Radar Works
There are two separate Safety Radar sys-
tems in limited use today: Safety Alert, and
Safety Warning System (SWS). Both sys-
tems use modified K-band radar signals.
From the factory, your Passport is pro-
grammed with safety radar decoding OFF.
If Safety Radar is used in your area, your
Passport will display these signals as K
band radar signals instead of safety radar
unless you use the EZ Programming to turn
Passport’s safety radar decoding ON.
The Safety Alert safety radar system
has three possible alerts:
• Safety Vehicle
• Road Hazard
• Train Nearby
The SWS safety radar system has 64
possible messages (60 currently allocated).
The SWS messages your Passport can dis-
play are listed on the facing page.
